Coordinate system - Wikipedia, the free encyclopedia |
 | | In the case that vector quantities are considered in relation to position and displacement, as in vector fields, a similarity transformation of space is normally accompanied by a corresponding linear transformation of the other vector quantities, to preserve angles between e.g. |
 | | The transformation is linear because, as opposed to position, most vector quantities have a natural origin, e.g. |
 | | Changing the basis is a coordinate transformation, a linear transformation that can be summarized by a matrix, and is computationally the same as a mapping of points to other points keeping the bases the same: e.g. |
